Fossil Pokémon

Fossil Pokémon are Pokémon which can be obtained from specific fossils.

All of these Pokémon are of dual Rock-Type, except for Cranidos. They all evolve at Level 40 with the exception of Cranidos and Shieldon, which evolve at Level 30, then Archen and Tirtouga, which evolve at Level 37, and Aerodactyl, who does not evolve at all. Any Fossil can be also found in the Underground in 4th Generation games.

Generation III Fossil Pokémon

These Fossils can be found in the desert area east of Lavaridge Town in Pokémon Ruby and Sapphire. They are in the Crumbling Tower which requires a Mach Bike to get to the top. They can be brought back to life by a Devon worker in Rustboro City. You can get the fossil you did not choose after beating the Elite 4 and going to the fossil maniac's house.
